[0025] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of the first embodiment of the sample detection device provided by the present application, Figure 2 is a schematic structural diagram of the second embodiment of the sample detection device provided by the present application. As Figure 1 and Figure 2 shown, the sample detection device includes a carrying component 10 and a pipetting component 20.

[0026] Specifically, the carrying component 10 includes a first loading seat 11 and a second loading seat 12. The first loading seat 11 is used to carry the reagent kit 110, and the second loading seat 12 is used to carry the reagent card 120. Among them, the reagent card 120 can be a detection item for rapidly detecting blood cells based on principles such as fluorescence immunochromatography and chemiluminescence, and the reagent card 120 is a blank reagent card 120 without the addition of the sample to be tested. The reagent card 120 is provided with a sample addition area 122. The pipetting component 20 is used to obtain the sample to be tested on the first loading seat 11 and add the sample to be tested to the sample addition area 122.

[0027] In one embodiment, the test kit 110 carried by the first loading seat 11 stores the sample to be tested. The pipetting assembly 20 is used to aspirate the sample to be tested from the test kit 110 and add the sample to the sample loading area 122 of the reagent card 120, so that the reagent card 120 can quickly test the sample to be tested. In another embodiment, the first loading seat 11 may be provided with two loading positions. One loading position is used to carry the blank test kit 110 without the sample to be tested, and the other loading position is used to carry the sample to be tested. The sample to be tested may be stored in a sample tube or a reaction cup, so that the pipetting assembly 20 transfers the sample to be tested at the other loading position to the sample loading area 122 of the reagent card 120. In other embodiments, the first loading seat 11 and the second loading seat 12 may be integrally provided or connected by other connecting components, which are not specifically limited herein.

[0028] In a possible embodiment, the pipette 22 of the pipetting assembly 20 only moves in the vertical direction. The sample detection device moves the carrying assembly 10 to a position below the pipetting assembly 20 through the driving motor 63, so that the pipetting assembly 20 aspirates liquid from the carrying assembly 10 or adds the liquid to a certain position of the carrying assembly 10. That is, as Figure 1 shown, when the first loading seat 11 is located below the pipetting assembly 20, the pipetting assembly 20 is used to obtain the sample to be tested from the first loading seat 11; when the test kit 110 includes a plurality of cell bodies arranged in a linear direction, the pipetting assembly 20 is also used to perform liquid transfer operations on the plurality of cell bodies, so that the sample to be tested is mixed with the reagent and a test solution suitable for impedance detection is prepared. The sample detection device can perform impedance detection through the test kit 110. As Figure 2 shown, when the second loading seat 12 is located below the pipetting assembly 20, the pipetting assembly 20 is used to add the sample to be tested on the first loading seat 11 to the reagent card 120 on the second loading seat 12.

[0029] Therefore, in order to enable the pipetting assembly 20 to add the sample to be tested on the first loading seat 11 to the reagent card 120 on the second loading seat 12, when the driving motor 63 only drives the carrying assembly 10 to move in a linear direction, the first loading seat 11 and the second loading seat 12 may be arranged side by side in the linear direction, or the carrying assembly 10 may be arranged through structures such as rotating parts and sliding parts, so that the first loading seat 11 and the second loading seat 12 can be swapped positions and are respectively located below the pipetting assembly 20; or, the first loading seat 11 and the second loading seat 12 can be respectively located below the pipetting assembly 20 by adding a driving motor 63 and a track. The user can adjust according to the actual design requirements, which are not specifically limited herein.

[0030] In an embodiment of the present application, the carrying component 10 of the sample detection device includes a first loading seat 11 and a second loading seat 12. The first loading seat 11 is used to carry the reagent kit 110 and the sample to be tested, or the first loading seat 11 is used to carry the reagent kit 110, and the reagent kit 110 stores the sample to be tested; the second loading seat 12 is used to carry the reagent card 120, and a sample adding area 122 is provided on the reagent card 120. The pipetting component 20 is used to obtain the sample to be tested on the first loading seat 11 and transfer the sample to be tested to the reagent card 120 for sample addition, realizing automatic sample addition of the reagent card 120. The operation is simple, which can effectively reduce manual intervention and improve the detection efficiency of the hematology analyzer.

[0031] In one embodiment, please refer to Figures 3 - 5 , Figure 3 which is a schematic structural diagram of the first embodiment of the carrying component provided by the present application, Figure 4 is Figure 3 a schematic structural diagram of the carrying component in a side view, Figure 5 and which is a schematic structural diagram of the second embodiment of the carrying component provided by the present application.

[0032] As Figures 3 - 5 shown, the carrying component 10 further includes a rotating mechanism 13. The first loading seat 11 and the second loading seat 12 are arranged in parallel. The pipetting component 20 is located above the first loading seat 11 and is used to obtain the sample to be tested. The rotating mechanism 13 is connected to the second loading seat 12, and the rotating mechanism 13 is used to drive the second loading seat 12 to rotate so as to rotate the sample adding area 122 of the reagent card 120 below the pipetting component 20.

[0033] Specifically, the first loading seat 11 and the second loading seat 12 are arranged in parallel, and the pipetting component 20 is located above the first loading seat 11. Among them, when the driving motor 63 drives the loading component to move in a linear direction, the first loading seat 11 and the second loading seat 12 can be respectively arranged on both sides of the linear direction. During the movement, the trajectory of the first loading seat 11 during movement is the first trajectory, and the trajectory of the second loading seat 12 during movement is the second trajectory. The pipetting component 20 can be located at any position on the first trajectory and is used to aspirate the sample to be tested on the first loading seat 11 at this position.

[0034] As Figure 3 and Figure 4 shown, when the rotating mechanism 13 does not rotate, the first loading seat 11 is located on the first trajectory and the second loading seat 12 is located on the second trajectory. At this time, the first loading seat 11 can be moved below the pipetting component 20 by the driving motor 63 for pipetting operation. As Figure 5 and Figure 2As shown, the rotation mechanism 13 is used to drive the second loading seat 12 to rotate and rotate the second loading seat 12 located on the second track to the first track. After the rotation mechanism 13 rotates, the sampling area 122 of the reagent card 120 on the second loading seat 12 is located below the pipetting assembly 20, so that the pipetting assembly 20 can add the aspirated sample to be tested to the sampling area 122 of the reagent card 120.

[0035] In the embodiment of the present application, the pipetting assembly 20 of the sample detection device is located above the first loading seat 11. The rotation mechanism 13 rotates the sampling area 122 of the reagent card 120 to below the pipetting assembly 20, so that the pipetting assembly 20 can obtain the sample to be tested on the first loading seat 11 and transfer the sample to be tested to the reagent card 120 for sampling, realizing automatic sampling of the reagent card 120, reducing manual intervention, with simple operation and effectively improving the detection efficiency of the blood cell analyzer.

[0036] Optionally, the rotation mechanism 13 includes a rotation motor 130 and a rotating shaft 131. The rotation motor 130 is connected to the rotating shaft 131, and the second loading seat 12 is fixedly connected to the rotating shaft 131. The rotation motor 130 is used to drive the second loading seat 12 to rotate along the rotating shaft 131. The reagent card 120 is placed on the second loading seat 12. The reagent card 120 includes a detection area 121 and a sampling area 122. The rotating shaft 131 is correspondingly arranged at one end of the reagent card 120 and away from the sampling area 122.

[0037] Specifically, the reagent card 120 includes a detection area 121, a sampling area 122 and a scanning area 123. The detection area 121 and the scanning area 123 are respectively located on both sides of the sampling area 122. The sample detection device is used to perform optical detection on the detection area 121 of the reagent card 120 to obtain the detection result of the sample to be tested. The sample detection device scans the scanning area 123 to obtain the barcode information of the reagent card 120. Among them, the rotating shaft 131 is correspondingly arranged at one end of the reagent card 120 and away from the sampling area 122, so that the sampling area 122 can be moved to the pipetting assembly 20 with a smaller rotation amplitude, reducing the space occupied by the rotation mechanism 13 and improving the space utilization rate of the sample detection device. For example, the rotating shaft 131 can be located on the side of the second loading seat 12 close to the detection area 121, or the rotating shaft 131 can also be located on the side of the second loading seat 12 close to the scanning area 123.

[0038] The sample detection device of this embodiment moves a first number of steps through the rotation motor 130 to drive the second loading seat 12 to rotate along the rotation shaft 131, so that the reagent card 120 on the second loading seat 12 rotates from the second track to the first track and is located under the liquid transfer assembly 20. And, after the liquid transfer assembly 20 adds the sample to be tested to the sample addition area 122 of the reagent card 120, the rotation motor 130 also needs to move in the reverse direction by the first number of steps, so that the second loading seat 12 rotates in the reverse direction and returns to the initial position. The sample detection device needs to perform optical detection on the reagent card 120 on the second loading seat 12 on the second track. Wherein, the rotation shaft 131 extends in the vertical direction, so that the rotation mechanism 13 can drive the second loading seat 12 to rotate in the horizontal direction, reducing the risks of sample leakage and reagent card 120 tipping over during the rotation process, and improving the reliability of the sample detection device.

[0039] Further, the rotation mechanism 13 further includes a motor fixing plate 132. The sample detection device further includes a guide rail 61 and a slider 62. The slider 62 is slidably connected to the guide rail 61. The first loading seat 11 and the motor fixing plate 132 are arranged in parallel and connected to the slider 62. The second loading seat 12 is connected to the motor fixing plate 132 through the rotation shaft 131.

[0040] Specifically, the loading assembly is connected to the guide rail 61 through the slider 62, so that the loading assembly can perform linear motion along the guide rail 61. The first loading seat 11 and the second loading seat 12 are arranged in parallel and are connected to the slider 62 through their respective fixing plates; for example, the first loading seat 11 is arranged on the slider 62 through the first plate body, and the second loading seat 12 is arranged on the slider 62 through the motor fixing plate 132, so that the first loading seat 11 and the second loading seat 12 are relatively independent. After the liquid transfer assembly 20 obtains the sample to be tested from the first loading seat 11, the rotation mechanism 13 drives the second loading seat 12 to rotate along the rotation shaft 131 through the rotation motor 130, so that the second loading seat 12 moves below the liquid transfer assembly 20.

[0041] In a possible implementation manner, the rotation mechanism 13 further includes a synchronous belt 136 and a pulley 137. The motor fixing plate 132 is used to fix the rotation motor 130. The rotation shaft 131 is connected to the motor fixing plate 132 through a bearing. A pulley 137 is sleeved on the rotation shaft 131. The pulley 137 is connected to the output shaft of the rotation motor 130 through the synchronous belt 136, so that the second loading seat 12 rotates relative to the motor fixing plate 132 under the drive of the rotation motor 130. Among them, the method of motor transmission through the pulley 137 is more stable, has high transmission efficiency, and is convenient for the rapid movement of the second loading seat 12.

[0042] Optionally, the pipetting assembly 20 includes a vertical motor 21 and a pipettor 22. The vertical motor 21 drives the pipettor 22 to move a first number of steps to obtain a sample to be tested on the first loading seat 11; the vertical motor 21 drives the pipettor 22 to move a second number of steps to add the sample to be tested to the sample adding area 122, and the first number of steps is greater than the second number of steps.

[0043] Specifically, since the height of the reagent kit 110 is usually relatively high, the height of the first loading seat 11 is generally lower than the height of the second loading seat 12 to facilitate placing the reagent kit 110 on the first loading seat 11. Moreover, in order to prevent the second loading seat 12 from easily colliding with the reagent kit 110 during rotation, when the reagent kit 110 is placed on the first loading seat 11, the rotation plane of the second loading seat 12 should be higher than the top of the reagent kit 110, so that after the rotation mechanism 13 finishes rotating, the second loading seat 12 is located above the reagent kit 110, and the reagent card 120 is located below the pipetting assembly 20.

[0044] The driving motor 63 is used to drive the loading assembly to move along a horizontal linear direction; the pipettor 22 of the pipetting assembly 20 is used to contact the liquid and perform operations such as sucking and discharging the liquid. The pipetting assembly 20 controls the pipettor 22 to move in the vertical direction through the vertical motor 21, so that the pipettor 22 can be located at different heights and perform the operations of sucking or discharging the liquid.

[0045] In this embodiment, when the pipetting assembly 20 does not perform pipetting operations, the pipettor 22 is located at the initial position, which is usually at the top of the sample detection device, so that the pipettor 22 is not easily collided with other internal components; when the pipetting assembly 20 needs to obtain a sample to be tested through the pipettor 22, the vertical motor 21 drives the pipettor 22 to move a first number of steps, so that the pipettor 22 descends from the initial position to a certain pool of the first loading seat 11 to suck the sample to be tested; after the pipettor 22 sucks the sample to be tested, the vertical motor 21 moves the first number of steps in the reverse direction and returns the pipettor 22 to the initial position, the rotation mechanism 13 rotates the second loading seat 12, and the vertical motor 21 continues to drive the pipettor 22 to move a second number of steps, so that the pipettor 22 descends from the initial position above the sample adding area 122 of the reagent card 120 and adds the sucked sample to be tested to the sample adding area 122, realizing automatic sample addition of the reagent card 120, reducing manual intervention, and effectively improving the detection efficiency of the blood cell analyzer.

[0046] Optionally, the rotation mechanism 13 further includes a limiting structure (not shown in the figure), and the limiting structure is used to limit the rotation angle of the reagent card 120.

[0047] Specifically, as Figure 5As shown in the figure, the limiting structure includes a first limiting block 134 and a second limiting block 135. The first limiting block 134 is arranged on the motor fixing plate 132, and the second limiting block 135 is arranged on the side of the second loading seat 12 away from the reagent card 120. The second loading seat 12 rotates along the rotating shaft 131, and the first limiting block 134 is used to abut against the first limiting block 134 to limit the rotation angle of the second loading seat 12, so that the second loading seat 12 stays in the current position and the sampling area 122 of the reagent card 120 is just located below the liquid transfer assembly 20.

[0048] In the embodiment of the present application, the rotation angle of the reagent card 120 is limited by the limiting structure, so that the second loading seat 12 can just stay below the liquid transfer assembly 20. The structure is simple and easy to implement; and it can effectively prevent faults such as the collision between the second loading seat 12 and other components and the detachment of the reagent card 120 caused by excessive rotation, improving the reliability of the sample detection device.

[0049] Optionally, the sample detection device further includes a guide rail 61 and a driving motor 63. The guide rail 61 is arranged on the bottom plate, the carrying component 10 is slidably connected to the guide rail 61, and the driving motor 63 is connected to the carrying component 10 and used to drive the carrying component 10 to move along the guide rail 61, so that the carrying component 10 moves to the sampling position, and the rotating mechanism 13 is used to rotate the second loading seat 12.

[0050] Specifically, the guide rail 61 is used to guide the carrying component 10 to move along a preset direction, so that when the driving motor 63 drives the carrying component 10, the carrying component 10 can be accurately moved to the preset position. The sample detection device may further include a push rod and a flange. The output shaft of the driving motor 63 is connected to the push rod. The push rod is used to receive the driving force of the driving motor 63 and rotate along the preset direction. The flange is sleeved on the push rod and connected to the slider 62 of the carrying component 10. The flange is used to receive the rotational force of the push rod and drive the carrying component 10 to move linearly, so that the first loading seat 11 is located below the liquid transfer assembly 20.

[0051] Furthermore, the sample detection device further includes an impedance detection component 30. The impedance detection component 30 is located on one side of the carrying component 10. After the liquid transfer component 20 adds the sample to be tested to the sampling area 122, the driving motor 63 is used to move the carrying component 10 to the impedance detection component 30, so that the impedance detection component 30 performs impedance detection on the sample to be tested in the reagent kit 110.

[0052] Specifically, the sample detection device may further include a base body, which may be composed of a substrate, side plates disposed around the substrate, etc. The loading assembly 10 is disposed on the substrate and moves along the horizontal direction of the substrate. The impedance detection assembly 30 may be disposed on one side of the loading assembly 10 and close to the side plate, or the impedance detection assembly 30 may be disposed on the side plate. After the pipetting assembly 20 adds the sample to be tested to the sample addition area 122, the driving motor 63 is used to move the loading assembly 10 and dock the reagent kit 110 on the loading assembly 10 with the electrode connecting member of the impedance detection assembly 30, so that the electrodes of the reagent kit 110 are electrically connected to the electrode connecting member. The impedance detection assembly 30 is used to perform an impedance counting test on the sample to be tested in the reagent kit 110.

[0053] In this embodiment, after the pipetting assembly 20 adds a sample to the sample addition area 122 of the reagent card 120, the sample detection device moves the reagent kit 110 to the impedance detection assembly 30 so that the impedance detection assembly 30 performs an impedance detection on the sample to be tested in the reagent kit 110, enabling the reagent card 120 to incubate the sample during the impedance detection process, saving the waiting time for incubation and improving the incubation efficiency.

[0054] Further, the sample detection device further includes a fluorescence detection assembly (not shown in the figure). The fluorescence detection assembly is located on one side of the pipetting assembly 20. After the impedance detection assembly 30 performs an impedance detection on the reagent kit 110, the driving motor 63 is used to move the loading assembly 10 to the fluorescence detection assembly so that the fluorescence detection assembly performs a fluorescence detection on the sample to be tested on the reagent card 120.

[0055] Specifically, the reagent card 120 includes a detection area 121. After adding the sample to be tested to the reagent card 120 and incubating the sample for a preset time, the fluorescence intensity of the detection area 121 of the reagent card 120 changes, enabling the fluorescence detection assembly to perform a fluorescence detection on the detection area 121 of the reagent card 120 and obtain the fluorescence detection result of the sample to be tested. At this time, the reagent card 120 is a detection article for rapid testing using the fluorescence immunochromatography method. The fluorescence detection assembly is used to read the fluorescence intensity of the detection area 121 and characterize the blood cell characteristics of the sample to be tested based on the fluorescence intensity.

[0056] In this embodiment, after the pipetting assembly 20 adds a sample to the sample addition area 122 of the reagent card 120, the sample detection device moves the reagent kit 110 to the impedance detection assembly 30 so that the impedance detection assembly 30 performs an impedance detection on the sample to be tested in the reagent kit 110; after the impedance detection, the driving motor 63 is further used to move the loading assembly 10 to the fluorescence detection assembly so that the fluorescence detection assembly performs a fluorescence detection on the sample to be tested on the reagent card 120, enabling the reagent card 120 to incubate the sample during the impedance detection process, saving the waiting time for fluorescence detection and improving the detection efficiency.

[0057] In other embodiments, the sample detection device may further include a biochemical detection component (not shown in the figure). At this time, the reagent card 120 may also be a detection article for rapid testing using the chemical staining method. After adding the sample to be tested, the biochemical detection component is used to perform optical detection on the reagent card 120 and obtain the biochemical detection result of the sample to be tested.

[0058] In one embodiment, the sample detection device further includes a scanning component (not shown in the figure). The reagent card 120 includes a scanning area 123. The scanning component is used to scan the scanning area 123 of the reagent card 120 to obtain the barcode information of the reagent card 120.

[0059] Specifically, relevant identification codes, two-dimensional codes, etc. may be set on the scanning area 123 of the reagent card 120. The scanning component can scan the scanning area 123 of the reagent card 120 by means of image recognition, etc. to obtain the barcode information of the reagent card 120. This barcode information can be used to indicate the qualification information of the reagent card 120, the relevant information of the sample to be tested, etc., so that the sample detection device can perform corresponding control based on the barcode information. For example, control the detection items of the reagent kit 110 through the barcode information, or give an alarm when the reagent card 120 exceeds the expiration date, etc. No specific limitation is made here.
